Powershell infected with wmail-blog, wmail-chat.com malware


Recommended Posts

I've seen this issue in several posts now and somehow I've been infected with the same malware/trojan.  If there's any help for my case I'd greatly appreciate it and it's possible this may have been used to breach security on a crypto wallet I have now had funds stolen from in the last couple days.  Very upsetting.

Hello @Teccmo  and  :welcome:

 

My name is MKDB and I will assist you.

 

 

Let's keep these principles as we proceed. Make sure to read the entire post below first.

  • Please follow the steps in the given order and post back the log files.
  • Please attach all log files into your post.
  • Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
  • Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
  • Searching, detecting and removing malware isn't instantaneous and there is no guarantee to repair every system.
  • Before we start, please make sure that you have an external backup, not connected to this system, of all private data.
  • Please be patient and stick with me until I give you the "all clear".
  • Only run the tools I guide you to. Please don't run any other scans, download, install or uninstall any programs while I'm working with you.
  • Cracked or hacked or pirated programs are not only illegal, but also will make a computer a malware victim. Having such programs installed, is the easiest way to get infected. It is the leading cause of ransomware encryptions. It is at times also big source of current trojan infections. Please uninstall them now, if any are here, before we start the cleaning procedure.
  • As English is not my native language, please do not use slang or idoms. It may be hard for me to understand.
  • If you do not respond within 4 days, your topic will be closed. If you are away for a longer time, please let me know.

 

 

 

Step 1

  • Please download the Malwarebytes Support Tool (MBST).
  • Run MBST and accept license agreement.
  • In the left navigation pane of MBST, click Advanced.
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine.
  • A zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file on your next reply.

Thank you for those logfiles @Teccmo.

 

We will run a fix with FRST (Step1) and do another scan with FRST as well (Step2).

With Step1, FRST will create a .zip file like < Date_Time.zip >, for example 20.02.2021_11.33.52.zip, on your desktop. Please upload that .zip file here or attach it with your next answer.
Thank you!

 

Step 1

  • Please download the attached fixlist.txt file and save it to your download folder, which is C:\users\BillFX\Downloads\ in your case.
  • You will find the file FRSTEnglish.exe (FRST) as well in this folder.

Note: It's important that both files, FRST and fixlist.txt are in the same location or the fix will not work.

  • Close all open programs and save your work.
  • Run FRST again.
  • Press the Fix button only once and wait. Please be patient and do not interfere, even if FRST does not respond for some time. That's nothing to worry about.
  • Please note: This Fix will remove all temporary files and empty recycle bin.
  • If the tool needs a restart, please make sure you let the system restart normally and let the tool complete its run after restart.
  • FRST will create one log now (Fixlog.txt) in the same directory the tool is run.
  • Please attach this logfile to your next reply.

 

 

 

Step 2

  • Run FRST again.
  • Check the box in front of Shortcut.txt.
  • Press the Scan button.
  • FRST will create three logs (FRST.txt + Addition.txt + Shortcut.txt) in the same directory the tool is run.
  • Please attach these logfiles to your next reply.

Thank you very much, very well done @Teccmo. 👍

Let's remove and search for some leftovers.

Please let me know: How is your system running at the moment? Does MBAM still block malicious sites?

 

 

Step 1

  • Please download the attached fixlist.txt file and save it to the location where you ran FRST from ( C:\Users\BillFX\Downloads\ ).

Note: It's important that both files, FRST and fixlist.txt are in the same location or the fix will not work.

  • Close all open programs and save your work.
  • Run FRST again.
  • Press the FIX button only once and wait. Please be patient and do not interfere, even if FRST does not respond for some time. That's nothing to worry about.
  • Please note: This Fix will remove all temporary files and empty recycle bin.
  • If the tool needs a restart, please make sure you let the system restart normally and let the tool complete its run after restart.
  • FRST will create one log now (Fixlog.txt) in the same directory the tool is run.
  • Please attach this logfile to your next reply.

 

 

 

Step 2

  • Run FRST again.
  • Copy and paste the whole content of the code box into the search field:
SearchAll: REOptimizer
  • Press the Search files button. Please be patient, this scan may take some time.
  • FRST will create one log now (Search.txt) in the same directory the tool is run.
  • Please attach this logfile to your next reply.

 

 

 

Step 3

Download Kaspersky Virus Removal Tool (KVRT) and save it to your download folder.

  • Select the Windows Key and R Key together, the Run box should open.
  • Copy and paste the following string into the line:

C:\Users\BillFX\Downloads\KVRT.exe -dontencrypt

  • Select „Ok“ in the Run box.
  • If the „Windows protected your PC“ window opens, select „More info“. A new windows will open, select „Run anyway“.
  • An EULA window from KVRT will open, tick all confirmation boxes then select "Accept".
  • A window from KVRT will open, select "Change Parameters".
  • In the new window ensure the following boxes are ticked:
    • System memory
    • Startup objects
    • Boot sectors
    • System drive
  • Then select "OK" and „Start scan“.
  • completed: If entries are found, there will be options to choose. If "Cure" is offered, leave as it is. For any other options change to "Delete", then select "Continue".
  • Usually, your system needs a reboot to finish the removal process.
  • Logfiles can be found on your systemdrive (usually C: ), similar like this:

C:\KVRT2020_Data\Reports\report_<data>_<time>.klr

  • Right click direct onto those reports, select > open with > Notepad.
  • Save the files and attach them with your next reply.
